BACKGROUND Nontuberculous mycobacteria (NTM) are found ubiquitously in the environment. Since exposure to NTM is universal, infection likely represents underlying host susceptibility factors. Anti-IFN-ɣ autoantibodies have been described previously in patients with NTM. Up to 88 % of patients with disseminated NTM or other opportunistic infections have high-titer anti-IFN-ɣ autoantibodies, comp...

A scaling model is presented to analyze the nonlinear rheology of unentangled polymer melts filled with high concentration of small spherical particles. Assuming the majority of chains to be reversibly adsorbed to the surface of the particles, we show that the emergence of nonlinearity in the viscoelastic response of the composite system subjected to a 2D shear flow results from stretching of t...

Brucella abortus S19 and RB51 strains have been successfully used to control bovine brucellosis worldwide; however, currently, most of our understanding of the protective immune response induced by vaccination comes from studies in mice. The aim of this study was to characterize and compare the immune responses induced in cattle prime-immunized with B. abortus S19 or RB51 and revaccinated with ...

Hydrogen uptake in zirconium alloys is a major limiting factor of nuclear fuel cladding as subsequent hydride precipitation can lead to potential failure via delayed cracking (DHC). The specific mechanisms DHC have been focus earlier research, however there still no clear definition the resulting crystallography and sizes at various temperatures crack propagation. In this work, novel thermo-mec...

4-Methylimidazole (4-MEI) is a simple nitrogen-containing heterocyclic compound, and recently classified as group 2B by International Agency for Research on Cancer (IARC). Caramel coloring is widely applied food coloring in many food products including coffee, carbonated beverages, beer and wine. In present study, ɣ-irradiation was applied to Caramel Color III to reduce the level of 4-MEI witho...

Atmospheric radioxenon analyses conducted under the Comprehensive Test Ban Treaty Organization (CTBTO) necessitates collection of air samples to quantify 135Xe, an indicator for nuclear explosions and reactor operations. Analytical instrument calibration these requires high quality, monoisotopic reference standards that are typically short lived, therefore must be produced shipped promptly moni...
